Association of anxiety, depression symptoms and sleep quality with chronic kidney disease among older Chinese

This study aimed to explore the association of anxiety, depression symptoms and sleep quality with chronic kidney disease (CKD) among older Chinese adults. A total of 1025 participants from the Chinese Longitudinal Healthy Longevity Survey (CLHLS, 2011–2012) were included in our study. The Generalized Anxiety Disorder scale was used to assess anxiety and the Center for Epidemiologic Studies Depression Scale was used to evaluate depressive symptoms. Logistic regression models were conducted to explore the odds ratios (ORs) and 95% confidential intervals (CIs). We found that anxiety, depression symptoms and poor sleep quality were positively associated with albuminuria, impaired estimated glomerular filtration (eGFR) and CKD, after adjusting for other covariates. For anxiety symptom, the ORs and 95% CIs were 1.20 (1.15–1.38) for albuminuria, 1.16 (1.12–1.35) for impaired eGFR and 1.18 (1.12–1.36) for CKD, respectively. For depression symptom, the ORs and 95% CIs were 1.15 (1.05–1.23) for albuminuria, 1.14 (1.05–1.20) for impaired eGFR and 1.14 (1.05–1.22) for CKD, respectively. Compared with good sleep quality, the OR and 95% CI of poor sleep quality were 1.12 (1.04–1.35) for albuminuria, 1.10 (1.02–1.30) for impaired eGFR and 1.11 (1.03–1.32) for CKD, respectively. And the positive association was more evident among females, body mass index ≥ 28, smoking and drinking adults. Anxiety, depression symptoms and poor sleep quality are positively associated with CKD. Future cohort studies are needed to confirm the results.
